非谓语作状语,与主句的主语之间的关系是被动的,用过去分词；是主动的用现在分词.
而being deeply moved by the boy,是动名词短语,常作主语或宾语或介词的宾语.
例句：Being exposed to sunshine too long will do harm to your skin.
The bird was lucky enough to escape being killed.那第二句是对的吗不对。因为此处是原因状语。所以不行。就是说Being句型不能用逗号吗？主要看它充当什么成分，而不是看逗号不逗号。如：Being exposed to sunshine ,if too long ,will do harmto your skin.
